Abstract: A multi-layer printed circuit board is constructed to suppress radio frequency interference (RFI) generated by high frequency clock and data signals therein. Suppression is achieved by positioning clock lines (254) carrying the clock signal on a first voltage reference layer (152) proximate to a second voltage reference layer (154). The two layers shield the clock signal from the signal lines on other layers. Noise may be further reduced by forming bridges (270) in the second voltage reference layer (154) proximate to the clock lines so that the bridges (270) span the width of the clock line. Capacitors are also preferably utilized to further suppress radiated noise. The capacitors provide AC coupling between the first and second voltage reference layers (152, 154) so that a low impedance path is provided for high frequency noise generated by the clock signal. The second voltage reference layer (154) thus operates as an effectively continuous shield between the bridges (270).

Abstract: On a produit une carte de circuits imprimés multi-couches permettant de supprimer les brouillages radio-électriques (RFI) créés par les signaux d'horloge et de données de hautes fréquences se trouvant dans ladite carte. La suppression est obtenue par positionnement de lignes d'horloge (254) portant le signal d'horloge sur une première couche (152) de tension de référence proche d'une seconde couche (154) de tension de référence. Les deux couches protègent le signal d'horloge des lignes de signaux se trouvant sur d'autres couches. On peut réduire davantage le bruit par formation de ponts (270) dans la seconde couche (154) de tension de référence proche des lignes d'horloge, de sorte que lesdits ponts (270) couvrent la largeur de la ligne d'horloge. On utilise également de préférence des condensateurs destinés à supprimer davantage le bruit émis. Les condensateurs assurent un couplage en courant alternatif entre les première et seconde couches (152, 154) de tension de référence, de sorte qu'un chemin de faible impédance est ménagé pour le bruit HF généré par le signal d'horloge. Ainsi, la seconde couche (154) de tension de référence fait office de blindage effectivement continu entre lesdits ponts (270).

Abstract: In a microwave device, for example a microwave local oscillator with a harmonic mixer for feedback control, problems of coupling the mixer circuit to the R.F. cavity (10) are overcome by providing a d.c. blocking capacitor of the mixer on a planar surface of a support (20) extending across an aperture (14) in one wall of the cavity. In preferred embodiments the capacitor is a planar device formed by a plurality of interdigitated fingers (26, 28). These fingers (26, 28) are oriented to couple magnetically with the R.F. energy at the aperture in the cavity (10). The support conveniently comprises a printed circuit board having a ground plane (22) on the same surface as the capacitor, which is located in a small opening (24) in the ground plane. A second ground plane (38) is provided on the opposite side of the printed circuit board, overlying the opening. The two ground planes are interconnected by plate-through-holes (40).
